Across the globe, gender equality is often seen as the key to leveling the playing field in education and careers. In many Western countries, women now outperform men in higher education, with opportunities widely available and traditional barriers removed. Despite this progress, a surprising trend emerges: women remain underrepresented in STEM fields.
This phenomenon is known as the gender equality paradox—a pattern showing that greater societal equality can coincide with more pronounced gender differences in career choices.
Academic Strengths and Career Paths
Research consistently highlights differences in academic strengths between boys and girls. On average, boys perform better on math and science assessments, while girls excel in reading comprehension and verbal skills. These differences influence career paths.
For example, individuals tend to pursue fields that align with their strongest academic skills: students who excel in math are more likely to enter STEM, while those strongest in reading often gravitate toward humanities or social sciences.
Psychologists and gender theorists have long debated the causes of these patterns. Are disparities the result of innate differences in ability, personal interests, or cultural expectations? For instance, the prevalence of male engineers and female nurses could be due to natural strengths, differing interests, or longstanding social norms that label professions as “masculine” or “feminine.”
This distinction matters because it informs strategies to close the gender gap.

Historically, social constructivist theories suggested that removing societal barriers would reduce gender disparities. Feminist theorists aimed to expand what is considered acceptable for men and women, ensuring both had equal access to all fields. The assumption was that if children were encouraged equally in any domain, professions would eventually reflect true gender balance.
Why Equality Does Not Eliminate Disparities
Contrary to expectations, increasing gender equality has not erased career differences. In fact, in many highly egalitarian countries—such as Finland, Norway, and Sweden—gender-typical career preferences are stronger. Adolescents in these nations show a higher likelihood of choosing “people-oriented” careers for girls and “thing-oriented” careers for boys. By comparison, this pattern is weaker in countries like Indonesia or Morocco.
One explanation lies in environmental stress. Psychologists note that in societies facing high stress—through malnutrition, disease, or other hardships—gender differences are less visible. Harsh conditions constrain opportunities and expression, which diminishes inherent strengths. In contrast, improved living conditions reduce stressors and social restrictions, allowing natural preferences and abilities to surface more fully.
A practical illustration involves potential under ideal conditions. Suppose one person could grow to 10 feet, and another to 5 feet. A 20% reduction due to stress would leave them at 8 feet and 4 feet, respectively. The difference shrinks under stress, just as societal pressures can mask innate differences in skills or interests.
Intraindividual Strengths and Academic Choices
Recent research emphasizes the role of intraindividual academic strengths—each student’s strongest subject, independent of overall achievement. Studies show that girls are more likely to excel in reading, while boys often show their strongest abilities in math or science.
Expectancy–value theory explains how these strengths shape educational choices. Students evaluate how well they expect to perform in a subject and how much they value it for future benefits. Those with strong math skills tend to pursue STEM, while those strongest in reading lean toward humanities or social sciences.
Large-scale longitudinal studies in the U.S. and globally support this pattern.

Most research has focused on average performance, but the gender equality paradox may be most relevant among high achievers, given the intellectual demands of STEM fields.
A 2025 study led by Finnish researcher Marco Balducci examined 1.6 million adolescents across 82 countries using three waves (2012, 2015, 2018) of PISA data. The study assessed high (95th percentile), average (5th–95th percentile), and low (5th percentile) achievers to understand intraindividual academic strengths.
Results confirmed stable patterns: girls consistently excelled in reading, boys in math and science, across countries, achievement levels, and years. Countries where boys had a larger advantage in math or science also saw girls with an even greater advantage in reading.
Most notably, the gender equality paradox appeared clearly: as national gender equality increased, so did the differences in intraindividual strengths. Egalitarian norms allowed both sexes to fully develop their existing advantages, rather than reducing disparities.
Balducci’s findings suggest that equality at a societal level encourages individuals to build on their natural strengths. For men, that might mean greater achievement in STEM; for women, stronger performance in reading or humanities.
This mechanism explains why gender-specific patterns persist—even intensify—in highly equal societies.
Understanding the Paradox
The gender equality paradox challenges assumptions about equality and career outcomes. Providing equal opportunities does not guarantee equal participation in every field. Instead, it allows individual preferences and strengths to guide career paths, often resulting in pronounced gender patterns in areas like STEM.
Research, including Marco Balducci’s 2025 study, shows that egalitarian societies help individuals develop their natural abilities, highlighting how biology, environment, and personal interests interact to shape outcomes.
Understanding this paradox can inform policies and educational practices that balance equality with individual strengths.
